FEBio2 implements plugins, which are dynamic libraries that allow users to extend FEBio’s capabilities without having to recompile the entire code. Instructions for building plugins can be found in the FEBio User’s Manual and Developer’s manual.
Plugins are submitted by developers independent of the FEBio project. Use at your own risk.
FEBioHeat 2 MBThis plugins allows FEBio to solve steady-state and transient heat transfer problems.

Wang-Shenoy Material 2 MBThis plugin implements the constitutive model by Wang et al. (Biophysical Journal, 107, 2014, pp:2592-2603). This novel material proposes a mechanism for long-range force transmission in fibrous matrices enabled by tension-driven alignment of fibers. In addition to the plugin file (Win x64 only), the zip file contains the source code and example problems.

FEBioChem 2 MBFEBioChem is a plugin that implements a solver for the non-linear reaction-diffusion-convection equations. It allows users to model chemical reactions in a non-deformable mixture framework. The chemical species are considered solutes that diffuse in a solvent but can also be bound to the solid phase of the mixture. This plugin replicates some functionality of the FEBioMix module, but since it assumes the matrix does not deform, many calculations can be optimized for improved performance. The plugin can also be used to solve traditional chemical reactions, without the mixture framework.

DataMap 1 MBThe DataMap plugin allows users to generate material parameter data that varies continuously between two surfaces in 3D space. The plugin interpolates the data to the underlying mesh independent of the type of mesh topology that has been used (e.g., trilinear hexahedron, quadratic tetrahedron, etc.).

PreStrain 2 MBMany biological tissues exhibit residual stresses in vivo. Residual stresses are usually characterized by pre-strain, which can be in situ strains (i.e. strain that exists in vivo, in the absence of loading), or residual strains (i.e. strains that exist after the tissue is excised from the body). This plugin implements a general framework for representing pre-strain in a finite element model using a method termed the pre-strain gradient approach. In contrast to previous computational methods for including pre-strains, it does not require physiological existence of a globally stress-free reference configuration or its computability. The methodology also addresses the issue of incompatibility of the pre-strain gradient with the reference geometry and provides ways to accommodate for discrepancies by either modifying the reference geometry or the applied pre-strain gradient. The method is described in detail in the manuscript:

Trans Iso Mooney-Rivlin (Gordon 1966) 897 KBThis plugin is based on the transversely isotropic Mooney Rivlin material in FEBio but adds a stress term based on the force-length-curve by Gordon et al. (1966) for the active contraction. With this plugin, you can easily change the muscle properties to accommodate different muscle types.

FEWarp 4 MBThe FEWarp plugin implements the Hyperelastic Warping deformable image registration algorithm developed by Weiss and colleagues. The method is based on the principles of nonlinear solid mechanics to allow objective tracking of large deformations and rotations and the concomitant determination of stresses within the deforming body. The approach may be applied to physical deformations that arise in mechanics as well as to non-physical deformations such as the inter- and intrasubject registration of image data. For the physical deformation case, the goal is to quantify the kinematics and the kinetics of the deformations. In the nonphysical case, only the kinematics of the deformations are sought. An overview of the algorithms implemented by the plugin can be found in the following book chapter:
